Experiencing double vision, or diplopia, while wearing contact lenses can be alarming. It's crucial to understand the potential causes and when professional help is necessary. This comprehensive guide will explore the reasons behind this issue, offering solutions and advice on seeking appropriate medical care.
What Causes Double Vision with Contacts?
Double vision isn't inherently caused by contact lenses themselves; rather, they can exacerbate or reveal underlying eye conditions. Several factors can contribute:
-
Incorrect Lens Prescription: This is the most common culprit. If your prescription is outdated or inaccurate, your eyes may struggle to focus properly, leading to double vision. Even a slight discrepancy can cause this discomfort.
-
Dry Eyes: Contact lenses, especially if worn for extended periods or with inadequate hydration, can lead to dry eye syndrome. Dry eyes can disrupt the normal lubrication and smooth movement of the eyes, contributing to double vision.
-
Eye Strain: Prolonged near-work activities, like reading or computer use, combined with contact lens wear, can significantly increase eye strain. This strain can lead to temporary double vision.
-
Underlying Eye Conditions: Double vision can be a symptom of more serious conditions, such as:
- Strabismus (Misaligned Eyes): Contacts might highlight a pre-existing misalignment that was previously unnoticed.
- Muscle Imbalance: Problems with the extraocular muscles controlling eye movement can cause diplopia.
- Neurological Issues: In rare cases, double vision can stem from neurological problems affecting the nerves controlling eye muscles.
- Corneal Issues: Conditions affecting the cornea, such as keratoconus or corneal ulcers, might manifest as double vision, especially with contact lens wear.
-
Improper Contact Lens Fit: Ill-fitting lenses can irritate the eyes and disrupt their normal function, triggering double vision.
Is Double Vision with Contacts Serious?
While sometimes temporary and easily remedied, double vision shouldn't be ignored. It's essential to determine the underlying cause. In some cases, it can signal a more serious medical issue requiring prompt attention. Persistent or worsening double vision necessitates a visit to your eye doctor.
How Can I Fix Double Vision Caused by Contacts?
Depending on the cause, several solutions exist:
-
Check Your Prescription: Schedule an eye exam to ensure your prescription is up-to-date and accurate. This is the first step in diagnosing and correcting many cases of contact lens-related double vision.
-
Improve Eye Lubrication: Use artificial tears or lubricating eye drops regularly, especially if you experience dry eyes. Consult your eye doctor about appropriate solutions for your situation.
-
Take Breaks: Regular breaks from near-work activities are crucial, particularly when wearing contact lenses. The 20-20-20 rule (every 20 minutes, look at something 20 feet away for 20 seconds) is helpful.
-
Correct Lens Fit: If your lenses feel uncomfortable or ill-fitting, contact your eye care professional for a lens fitting adjustment.
When Should I See an Eye Doctor About Double Vision?
You should consult an ophthalmologist or optometrist immediately if:
- The double vision is sudden or severe.
- The double vision is accompanied by other symptoms, such as headache, nausea, or vision loss.
- The double vision persists despite trying home remedies.
- You experience double vision with or without contact lenses.
Can Contact Lenses Actually Cause Double Vision?
No, contact lenses themselves do not directly cause double vision. However, they can reveal or worsen pre-existing conditions that lead to double vision.
What Types of Contacts Are More Likely to Cause Double Vision?
No specific type of contact lens is inherently more likely to cause double vision. The key factor is the correct prescription and fit for your individual eyes and needs. Poorly fitting lenses, regardless of type, are more likely to lead to discomfort and potential vision problems.
Addressing double vision promptly is key to maintaining good eye health. Remember, a comprehensive eye exam is your best tool for diagnosing the cause and finding the right solution. Never hesitate to contact your eye care professional with any concerns about your vision.
